What is the difference between the two and what would you use for what application?

Any suggestions on where to get these products?
TIA

luster dust is glittery with color

petal dust is flat, no glitter, color only...mostly used for flowers.

pearl dust is just like it sounds...it has a suble sheen to it, not really glitter...much like a string of pearls.

disco dust is the opalescent, glittery, but totally awesome dust that resembles fairy dust.

not sure why it's not posting the rest of my message. i'll abbreviate in order to get the rest to show up:
